Alexandre Edmond Becquerel, a French physicist, discovered photovoltaic effect in 1839 and thus unraveling the key principle to today's solar energy cells. In this, the supply of light and/or heat releases positive and negative charge carriers (photovoltaic effect), generating electricity which can directly charge batteries and power motors. This direct conversion of sunlight into electricity ( Photovoltaics ) has continually been developing in recent decades. The advantage of photovoltaics is generating clean, environmentally-friendly electricity independent of the utility grid.

Today's solar cells are made almost entirely from semiconductor silicon. This atom exists in the form of silicon dioxide (quartz, sand) as unprocessed raw material in the earth's crust. It is the second most common element after oxygen. Silicon dioxide can be processed into monocrystalline, polycrystalline, or amorphous silicon. The differences lie in the respective energy conversion efficiency, which is crucial for the performance of a solar cell. Solar cells made of amorphous silicon have the lowest energy conversion efficiency and solar cells made of monocrystalline silicon have the highest energy conversion efficiency.

Small gadgets make up the largest share of household power consumption. This is usually due to the large number of small devices in modern households, from mixer to electric toothbrush, and not to the high power consumption of each single gadget. There are increasing numbers of electrical devices.In our shop you will find a selection of solar-powered household and portable devices. They even work when there is power grid failure and can even cut down on your electricity bill.

Fountains enable you to add charm and create a relaxing area in your garden with relatively little effort. Solar-powered fountains are environmentally friendly and energy saving. They function by means of photovoltaics. They are equipped with solar cells, which collect the sun's rays and convert them into electricity. Decorative fountains must be placed in a sunny location in the garden to ensure optimum functionality. You need the sun to power the fountain pump using the solar panel. The larger the amount of water, the higher the pump power and the more electricity you will need. The higher the fountain, the more solar cells you need to install. The lifespan of the pump also plays an important role. Solar-powered garden fountains do not necessarily have to be decorative fountains. They can also be functional fountains, which are used to improve the oxygen supply and to circulate water in garden ponds. A solar fountain rechargeable battery, which is charged with solar energy during the day and supplies the pump with electricity at night, make up for the power loss in the dark so you can also run them at night. Solar-powered illuminated fountains should also be equipped with a rechargeable battery.
